Question 1: What is the key function of the envelope?

Answer:

maintaining vacuum

Question 2: A two-filament arrangement within the x-ray tube

Answer:

dual focus

Question 3: Used to reduce the effective area of the focal spot

Answer:

line-focus principle

Question 4: An anode assembly that is immobile

Answer:

stationary anodes

Question 5: A structure where the primary x-ray beams exit the envelope, which allows less absorption or scatter of photons.

Answer:

window Question 6: The portion of the anode where the high-voltage electron stream will impact; describes the circular path that will be impacted by the electron beam.

Answer:

focal track

Question 7: What is the most common diagnostic radiography target angle?

Answer:

12 degrees

Question 8: Atomic number of Molybdenum

Answer:

42 Question 9: Photons that were not produced at the focal spot; also called off-focus radiation.

Answer:

extrafocal, radiation Question 10: A type of tube that quickly regulates the flow of electrons, producing x-ray photons.

Answer:

grid-controlled

Question 11: An anode assembly that turns during exposure

Answer:

rotating anodes

Question 12: Consists of the anode, stator, and rotor.

Answer:

anode assembly

Question 13: A small coil of thin thoriated tungsten wire

Answer:

filament Question 14: Photons that were not produced at the focal-spot; also called extrafocal radiation.

Answer:

off-focus radiation Question 15: A shallow depression in the cathode assembly designed to house the filament

Answer:

focusing cup Question 16: The parts within the cathode assembly that connect the elements of the assembly

Answer:

wiring Question 17: The positive side of the x-ray tube; serves as a target surface for high-voltage electrons from the filament, conducts the high voltage from the cathode back into the x-ray generator circuitry, and serves as the primary thermal conductor.

Answer:

anode Question 18: The portion of the anode where the high-voltage electron stream will impact the

Answer:

target Question 19: A very small focal spot; usually a fraction of a millimeter in size.

Answer:

fractional focal spot

Question 20: The physical area of the focal track that is impacted

Answer:

actual focal spot

Question 21: The portion of the anode where the high-voltage electron stream will impact?

Answer:

focal point Question 22: Permits the calculation of the time necessary for the housing to cool enough for additional exposures to be made.

Answer:

housing cooling charts Question 23: The entire cathode and anode assembly is housed within this metal structure?

Answer:

protective housing Question 24: Which term represents the circular path that will be impacted by the electron beam?

Answer:

Focal Track Question 25: Permits the calculation of the time necessary for the anode to cool enough for additional exposures to be taken

Answer:

anode cooling charts Question 26: The negative side of the xray tube; produces a thermionic cloud, conducts the high voltage to the gap between the cathode and the anode, and focuses the electron stream as it heads for the anode.

Answer:

cathode Question 27: Photons that were not produced at the focal spot; also called off-focus radiation.

Answer:

extrafocal radiation
